To all whom t may concern.-

Beit known that I, NATHAN HARPER, a citizen of the United States,residing in Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements inDrier-Cars forBricks; andI do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, aud to letters of referencemarked thereon, which form a partof this specification.

The object of this invention is to provide a drier-car for bricks orother clay products, whereby a large saving can be eected in the amountof fuel heretofore required in the drying process, while by the samemeans the capacity of the car and also of the dryingchamber are bothlargely increased without any addition to the size of eit-her.`

The invention consists in the improved drier-car and the combination andarrangements of the various parts thereof, substantially as will behereinafter more fully described, and finally embodied in the clauses ofthe claim.`

Similar letters of reference `indicate corresponding parts in each ofthe several figures.

Figure l is a side elevation of my improved drier-car, together with itsload of pallets carrying the bricks. Fig. 2 is a similar view of anordinary drier-car, drawn to the same size as Fig. 1, and illustratesthe dilference in the respective capacity of the two structures and inthe disposition of the load on each. Fig. 3 is an end elevation of Fig.l, placed in a drying-tunnel, and illustrates how completely the load onthe improved car occupies all the space availablewithin the tunnel. Fig.4 is a top plan view of the improved car, and Fig. 5 is an enlargedsectional view on line Fig. 4.

In said drawings, a a represent the side bars or frame of the improvedcar, which are secured and held firmly in their respective positions byrods or braces c or in any other desired manner. Projections el extendupwardly from said side bars to receive or sustain boxes or bearings eand axles f carrying wheels g, all of which are secured in theirrespective places by any of the usual means.

tially all the space from the surfacev of the.

rails to the top of the drying-tunnel B to be occupied with bricks. Thetop of said side bars or frame may of course be constructed -at anyheight desired below the top of the wheels.

Should the top of said frame be'carried high The pallets h, containingthe bricks enough to receive the axles of the wheels, the

upwardly-extendin g projections would in such case have nothing tosustain but the brick pallets placed thereon.

In all drier-cars heretofore used the top of the frame or sidel bars hasalways been arranged as high or higher than the top of the wheels, asillustrated at o', Fig. 2, whereby all the space between the top of saidframe and the surface of the rails i has been unoccupied with bricks,therefore unutilized. As thus constructed the area of the unoccupiedspace beneath the car is nearly equal in extent to the combined area ofall the spaces between the bricks, and as this latter area is divided bythe bricks into a `largenumber of narrow channels which greatly impedethe passage of the air-currents, while all the space beneath the car isunited in one large open channel, the result is that fully one-half 'ofall the heated air drawn through the drying-chamber passes beneath thecar without coming in oontact with the ,bricks thereon and is thuswasted, thereby causing the loss of about onehalf the fuel used. On myimproved car the bricks can be loaded close down to the surface of therails, thus compelling substantially all the air traveling through thedrying-chamber to pass directly between the various courses of bricks,thereby utilizing the heat to the fullest possible extent and reducingthe consumption of fuel in a corresponding degrec.

By comparing the load on the improved car,
